Design & Methodology Evaluation criteria of transportation systems and economic-financial analysis methods of transportation projects were implemented. Originality It is the first detailed study describing the evaluation criteria of public transportation systems and comparing the results obtained on two different routes in the economic-financial evaluation of public transportation projects. It is a guiding study for municipalities, decision-making institutions and other public transportation feasibility studies. Findings The necessary conditions for the implementation of the monorail system and how the public transportation projects should be evaluated in terms of the national economy-operator institution were determined. Conclusion In the economic analysis (from the national economy point), in order to obtain feasible results, it could be sufficient to increase the number of daily passengers to 55 thousand or decrease the construction costs to 15 million $/km. For financial analysis (from investor point), the construction cost of 10 million $/km or 67 thousand passengers per day could be sufficient to cover half of the cost.

Monoray sistemi gelişmekte olan ülkelerde tramvay, hafif raylı sistem ve metroya göre daha az tercih edilmektedir. Bu çalışmada, monoray sisteminin geleneksel raylı sistemlere alternatif olma olasılığı teknik ve ekonomik açıdan incelenmiştir. Özelliklerinin 21. yüzyıl teknolojisi ve gereksinimlerine uygun olduğu tespit edilmiştir. Monoray'ın gelişmekte olan ülkelerde uygulanabilirliğinin ekonomik incelemesinde; Eskişehir, seyahat ve maliyet verileri kullanılarak iki ayrı hat üzerinde ekonomik ve finansal fizibilite çalışmaları yapılmıştır. Eskişehir sonuçlarına göre Türkiye dahil %10 güncelleştirme oranına sahip ülkeler için ekonomik analizde günlük yolcu sayısının 55 bine yükselmesi veya inşaat maliyetlerinin 15 milyon $/km'ye düşmesi yeterli olabilir. Ayrıca güncel verilerle, uygulanabilir olması için yaklaşık %8'lik bir güncelleştirme oranı yeterli olabilir. Mali analiz sonuçlarına göre maliyetlerin çoğu %10'luk bir güncelleştirme oranı ile karşılanamamış ve mali durum desteği gerekebilir. Mali analiz için pozitif bir güncelleştirme oranı oranı uygulanabilir olması için yeterli olmayabilir.

Monorail System Feasibility Study for Developing Countries: The Case Study of Eskişehir-Turkey ABSTRACT The monorail system is one of the environmentally friendly, high-speed and high-capacity public transportation systems that have been used for more than 100 years. The Monorail system is less preferred than the tram, light rail transit and metro in developing countries. In this study, the possibility of the monorail system to be implemented an alternative to the traditional rail systems was examined in technical and economic terms. It has been determined that its features are in accordance with 21st-century technology and requirements. In the economic examination of the applicability of monorail in developing countries; by using the travel and cost data of Eskisehir-Turkey, economic and financial feasibility studies on two separate lines were made. According to the results of Eskişehir, for the countries which have 10% discount rate including Turkey, an increase in the number of daily passengers to 55 thousand or a decrease in construction costs to 15 million $/km could be sufficient in the economic analysis. Also, with current data, a discount rate of about 8% could be sufficient to be feasible. For financial analysis, the majority of costs could not be covered at a 10% discount rate and financial state support could be required. For financial analysis, a positive discount rate could not be sufficient to be feasible. Keywords: Public transportation systems, monorail, economic and financial feasibility, sensitivity analysis. 1. INTRODUCTION The lack of proper planning of the public transport systems/network causes people to use automobiles. The Since the industrial revolution, the rate of urbanization increase in the number of automobiles causes traffic has been increasing every year. While the proportion of congestion and consequently this seriously damages the people living in the urban areas was 46.69% in 2000, it increased to 55.71% in 2019 [1]. Moreover, the rapid health of people and the national economy [3]. In the increase in the total population has increased the urban USA, federal and local governments spent $209 billion in 2007, $218 billion in 2008 and $160 billion in 2009 population much faster. With the increasing urban to mitigate the effects of increased traffic congestion population, the demand for travel has increased, cities [4]. In addition, the increased time spent in traffic and have grown in area and mobility by using vehicles has the number of automobiles causes environmental become mandatory for people. The bicycle, which is one of the personal vehicles, does not have its own lane pollution. [5]. Despite efforts to reduce the use of fossil in many countries, affected by long-distance and terrain- fuels today, it is important to reduce automobile use simply because transportation modes are still dependent weather conditions. The motorcycle is not safe and has a on fossil fuels. For example, 28% of the total high mortality rate. These reasons have obligated people greenhouse gas emissions in the USA originate from to use public transportation or automobile [2]. transportation [4].
